Specification of Letters Patent.

Patented May 23, 1916,

Application filed June 23, 1915. Serial No. 35,971.

To all whom it may concern Be it known that I, LoUIs VON NAcY, a citizen of the United States, residing at Fort Howard, in the county of Baltimore and State of Maryland, have invented new and useful Improvementsin Drawing- Boards, of which the following is a specification.

The present invention relates to improvemembers, a board arranged above the side members and having brackets which are pivotally secured to the said sides and to provide one of the sides with a spring pressed latch which is vertically movable in the said side and which is adapted to co-act with one of the brackets to hold the bracket and the board supported by the bracket at a desired angle, and to further provide an operating pedal which operates the latch to permit of the swinging of the board.

A further object of the invention is to construct a device of this character which will embody the desirable features of simplicity, cheapness, efficiency and accuracy.

With the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claim.

In the drawing: Figure 1 is a front elevation of a drawing board or table constructed in accordance with the present invention, Fig. 2 is a side elevation, parts being shown in section, and illustrating the table by the dotted lines arranged at an inclination.

In carrying out my invention I propose to provide a frame comprising two side members of a similar construction, both indicated by the numerals 1. Preferably, but not necessarily, the side members 1 have their ends bifurcated, as at 2, to receive therein peripherally round bracket members 3 that are connected to a table or board 4. The members 8 are each provided with a transverse or connecting element 5 through which is passed a pivot rod 6 that passes through suitable openings in the side mem-- bers 1 of the frame. The side members preferably lnclude spaced legs 7 which term nate in feet 8 and these feet are provided wlth openings for the reception of securing elements, and whereby the board may be secured upon a floor or other support.

The leg members 7 have upper and lower connectmg members, indicated by the numerals 9 and 10 respectively, the upper member of one of both of the sides being formed with a bearing 10 for the reception of the enlarged end of a vertically movable latch member 11. The latch member has its upper end provided with a reduced extension or pm 12 which is adapted to be received in one of a number of spaced perforations 13 provided upon one of the peripherally rounded brackets 3. The latch member is formed wlth a reduced extension 14 which passes through a suitable opening 15 in the lower connecting member 10 of the side member 1, and surrounding the reduced member 14 and bearing against the connecting or brace section 10 of the shoulder provided between the member 14 and the member 11 is a helical spring 16 which, of course, forces the member 11in an upward direction and as a con sequence its reduced end or pin 12 into contact with the lower periphery of the bracket 3 as well as in engagement with one of the perforations or openings 13.

The numeral 17 designates a pedal which is hingedly secured, as at 18, to the member 10 of the frame, and the numeral 20 designates a link connection between the member 11 and the pedal 17. The pedal 17 is ar ranged in a convenient position to be operated upon by the draftsman.

From the above description, taken in con 7 sides being centrally provided with a bear- 7 each comprisinga'pair of legs which are connected at then upper ends, said upper ends being pivotally secured to the connect-- in}; elements for the arms of the arch-shaped members, an upper and a lower brace mem ber connecting the legs of the side members, and'the upper brace member of one of the ing, a latch member arranged for slidable movement in the bearing and having its upper end formed with a reduced portion which is'adapted to be received in the open- 7 ings in the mentioned arch-shaped member,

said latch member having its lower end formed with a reduced extension passing through an opening in the lower connecting member of the legs of the mentioned side of the frame, a spring surrounding the said reduced portion of the latch and exerting a tension between the mentioned brace and the 20 shoulder of the latch, a pedal having an angular end which is pivoted to the said lower brace of the referred to side, and a LOUIS VON NAGY.
